Girls Aloud placed each of the 12 singles from their first three albums -- 2003's Sound of the Underground, 2004's What Will the Neighbors Say?, and 2005's Chemistry -- within the Top Ten of the U.K. singles chart. Each one of the singles can be found on The Sound of Girls Aloud: The Greatest Hits, a straightforward compilation that makes for an ideal introduction to Girls Aloud, a group that has never had any form of stateside push. ~ Andy Kellman, All Music Guide
